Chalk myths...

Tonight I heard of some younger transwomen who were found eating chalk beucase they heard it can "raise your voice". I've never heard this myth and wonder if anyone else has. I did a little research and found this on chalk, but nothing so far to explain why they would have thoght that.

"Chalk is made from calcium carbonate. It is what many manufacturers use to make calcium supplements. Since it is from rock that is not a living source and is very bad for you to consume. It can cause kidney stones and does, in many people that take calcium tablets in excess where this rock mineral is used. The body's bone content of calcium is only made up of about 10% of this type of calcium and when people take this type of supplement, think it's good for them, they end up doing more harm than good. The body looks at this as toxic and if it gets absorbed, the liver deals with it mostly as a toxin rather than a nutrient."

I'm perplexed and concerned, expically if other folks are, uhh, biting into this myth!
